Segments are a method to define an audience for a Mailing. Symphonie supports
four segment types: a wizard-based segment, a fixed segment, a SQL segment, and a stored procedure
segment. Wizard segments can be created in the web site interface and allow conditions to be defined
for the selection, like Age is between 20 and 30 and it's within two weeks of their birthday. Do to the
complexity of these conditions, wizard segments cannot be created using the API. Fixed segments are
a 'fixed' set of email addresses that you upload and remain constant. The results of a wizard-based
segment may change over time as different recipients meet the conditions, but a fixed segment will
always be the same recipients. SQL and stored procedure segments can be created using the web site interface.
The recipient list for a mailing can be uploaded to the mailing itself, but if you are send to the
same group of recipients over and over, you may find it easier to define the group of recipients
as a segment, and then set the audience of the Mailing to that Segment.
Segments in Symphonie are not constained to a 'list'. You can target any recipient in the system with
a segment. Symphonie will automatically remove any recipients that have unsubscribed.
